GM MDI Scan tool

GM MDI is a new GM Diagnostic tool.it is not only work for the new gm car,but also for the old kind of car.it can test GM car from 1990---2012 year gm car.

GM MDI package components:

A. GM MDI wireless
B. J1962 Diagnostic connector
C. USB cable
D. Ethernet cable
E. AC adapter/power supply
F. batteries
G.CD manual
Operating software for the MDI will be downloaded from the TS2WEB website.
The GM MDI allows the user to perform Pass-Thru programming procedures using software running on a laptop or desktop PC.

What Protocols does the GM MDI Support?
For immediate use -- At present,vehicles have two buses on the 16 pin connector (high speed and low speed GMLAN).
The GM MDI communicates using all of the existing GM protocols, the same as the Tech2:
– UART
– Class 2
– KWP2000
– GMLAN (CAN)
For future use -- Global architecture coming in July 2008 for MY 2009 will use a total of 4 GMLAN links. (This is
a limited rollout in MY 2009.) Global architecture adds a medium speed bus and an expansion bus. The Tech 2 and
CANdi module can run only low and high speed, and won't work on the 4 GMLAN link system for diagnostics or programming. The MDI will have this capability.

How is the GM MDI Connected?
The GM MDI will be connected between the vehicle and the PC using the DLC and cable.Connection between the GM MDI and the PC can be accomplished several ways:
– Using the supplied cable to connect the mini USB port on the GM MDI and the USB port on the PC
– Using a standard CAT5 cable toconnect the Ethernet port on the GM MDI and the Ethernet port on the PC
– Using the WLAN card built into the
GM MDI to communicate with the PC through the dealerships wireless network.

How Will the GM MDI be Used?
The GM MDI is initially being introduced with Pass-Thru programming capabilities only. It can be used to perform Pass-Thru programming on all vehicles built since 1993 and will support all vehicles into the future.
The GM MDI will be required to perform diagnostics on selected NAO vehicles for model year 2009. Diagnostic software is scheduled to be released for the GM MDI during the fourth quarter of 2008. When diagnostics are introduced, the MDI will also get a remote data record capability. This permits recording data during a road test, similar to the Tech 2 Snap Shot function. A trigger switch connector is provided for this purpose.
Regulations require programming procedures to be compliant with SAE Recommended Practice J2534. The GM SPS is compliant with SAE Recommended Practice J2534, and the GM MDI is compliant with the portions of SAE J2534 that are applicable for GM vehicles.
